' the general direction ofthe device'is-shown as extending parallel; with the frame of-the car, although. it night preferably be arranged so astoextend downwardlyand rear wardly from a point onfithe franie approxi-" inately just above the axle.

According to the present invention," the,

drum 1 is fixedly secured to the frame 2 by means of the bolt or post which hasfthe' nuts 4 and 5 engaging. th'e fra ne and the j drum 1, respectively. v The post; 3 is vprovided with a nonecirculargportion 6 interinediate itsfendsandadapted to engage in a I correspondingly shaped opening in theplate 7 which. in turn hasithe tongue 8. engaging 1 thelower par-t oflthefiframel The nonf'o'i-r cular portion fiengages'ajlso in a correspondingly shaped opening' in the one wall. of the drum 1 and with this arrangement the drum is prevented from turning. Extending above the drum 1 there is provided the brake band 9 with its lining 10 of suitable fibrous material similar to-that usedfor lining the'wel'l knowniautomobile brake. bands.

The brake band and lining: are both slotted, 1 as indicated:at 1l,to receive the ear 12 on the 1 drum itself, this arrangement constituting a ineans'of centering the band on the drunn "llhe one end ot the brake band is anchored at. the point 13 to-thearm ltwhich in turn is freely- 'mounted upon; the; post, '3. By

"f The operation i is :as follows; Upon; conipression got the; spring of the automobile ori' other i VBhlQl? Cit 15130 sudden lowering; moves 7 'ment of the body of the car upon striking with it the arms 14 and 21 whichare mounted thereupon. By virtue of the spring 15, which tends to move the arm 14 upwardly, the cable 18 will be maintained in taut condition; and by virtue of the spring 21 the arm 21 will tend to follow, the arm 14 so as to maintain these parts in contact and thereby prevent objectionable noise. The brake band will at the same time be maintained in snug position about the drum. Then when the springs of the automobile are released and the body of the car begins to move upwardly with what would otherwise result in thefamiliar objectionable rebound,

; the initial upward movement of the drum,

which of course follows upwardlywith the car frame, will cause relative effective downward movement of the arm 14 with the consequent effective downward pull upon the end 18 of the brake band so as to gradually tighten the same about the drum and effect the initial snubbing action. Then when there has been sufficient movement .of the arm 14 to cause the contact nut 30 to engage the drawings, so that the brake band will be slipped bodily about the drum after having already been effectively tightened by the initial relative downward movement of the arm 14 alone. Such bodily slipping movement of the brake band about the drum produces an effective snubbing action so as to prevent the objectionable rebound and perj mits the car frame with the body to move upwardly in a gradual manner and at the I same time without any sudden shock which might otherwise be caused by a sudden checking of the upward movement of the car frame.

By. adjustment of the nuts 28, 30 and 31, the exact point when the arm 21 will be -moved together with the arm 14 in the manner just now described can be varied accordlng to the conditions of the springs of the car as well as other prevalent conditions which have to do'with rebound action. Thus it will be'seen that I have provided an effective device for checking or snubbing the objectionable rebound and have provided adevice which possesses the well known and effective brake band action, without however, requiring an unduly great length of brake band and lining. In this way I'have been able to reduce the cost of manufacture of such a device, considering the initial cost as well as the cost incident to renewal of lining as may be necessary from time to time. Another advantage resides'inthe quietness of the device, as well as the smoothness due to the gradual manner of operation of the present form of device. 7

'Itis to be understood that the present showing is only for purposes of illustration and that the structure here shown may be varied according to the principle of the present invention as herein set forth.

, What I claim is:

1. A. shock-absorbing device for vehicles, comprising a drum adapted to be fixedly mounted upon the vehicle frame, a brake band surrounding said drum, and means in cluding a plurality of arms mountedfor cooperative movement about the axis of the drum and actuated by rebound tendency to cause the bandto be tightened about the drum. 2

2. A shock-absorbing device for vehicles, comprising a drum adapted to be fixedly. mounted upon the vehicle frame, a brake band surrounding said drum, and means including a plurality of arms mounted for cooperative movement about the axis of the drum and actuated by rebound tendency to cause the band to be tightened about the drum, said arms having limited approach to cause the band to thereafter slip'bodily along the drum.

3. A. shock-absorbing device for vehicles, comprising adrum adapted to' be fixedly mounted upon the vehicle frame, a brake band surrounding said drum,'and"means including a plurality of spring-pressed arms mounted for (Bo-operative movement about the'axis of the drum and actuated by rebound tendency to cause the bandto be tightened about the drum. i

.4. A shock-absorbing device for vehicles, comprising a drum adapted to be fixedly mounted upon the vehicle frame, a brake band surroundingsaid drum,- and means including a plurality of arms mounted for co operative movement about the axis of the drum and having an inter-locking relation for causing said band to slip bodily about the drum in response torebound tendency.

5. A shoclnabsorbing device for vehicles, comprising a drum adapted to be fixedly mounted upon the vehicle frame, afbrake band surrounding said drum,a plurality of armsmounted for movement about the axis of said drum and having'the two ends ofsaid band attached thereto respectively, and operative connections between said arms and the vehicle axle, whereby rebound tendency causes effective engagement of the 'band about the drum. 7

'6. A shock absorbing device for vehicles,

comprising a drum adapted tov be fixedly IDOUDtQd upon the vehicle frame, a brake bend surrounding said drum, a plurality of arms mounted for movement about the axis of said drum and having the two ends of said band attached thereto respectively, a flexible connectlon between one of said arms I and the vehicle axle, and an operative conneat-ion between said arms, whereby tightening of the band about the drum is automatically effected in response to rebound tendency;

In testimony whereof I hereby afiix my signature.
